Can we have two output parameter in stored procedure?

A stored procedure can have many output parameters. In addition, the output parameters can be in any valid data type e.g., integer, date, and varying character. Second, after the SELECT statement, we assigned the number of rows returned by the query( @@ROWCOUNT ) to the @product_count parameter.

Which is better view or stored procedure?

A view is essentially a saved SQL statement. Therefore, I would say that in general, a stored procedure will be likely to be faster than a view IF the SQL statement for each is the same, and IF the SQL statement can benefit from optimizations. Otherwise, in general, they would be similar in performance.

How many values can be returned from a stored procedure?

A Stored Procedure can have any number of output parameters. The simple logic is this — If you want to return 1 value then use 1 output parameter, for returning 5 values use 5 output parameters, for 10 use 10, and so on. In this Tutorial I will explain how to return 3 values from a Stored Procedure in C# language.

How do I return a stored procedure table in SQL Server?

Why drop table if exists?

Why you should not use stored procedures?

Stored procedures are difficult to unit test. With an ORM, you can mock your database code so as to be able to test your business logic quickly. With stored procedures, you have to rebuild an entire test database from scratch. Stored procedures offer no performance advantage whatsoever.

How do I return the number of rows affected by a stored procedure?
